BALL COCK.

Application Med January 9, 1912. Serial Io. 587,928.

To all whom it may concern:

Be it known that I, WILLIAM' Srrnnwoon, a citizen of the United States, resldln at Detroit, -county of Wayne, State of Michlgan, have invented a certain new and useful Improvement in Ball Cocks, and declare the following to be a full, clear, and exact description of the same, such as willenable others skilled in the art to whlch 1t pertains to make and use the same, reference bein had to the accompanying d rawlngs, whic form a part of this speclficatlon.

M invention relates to water inlet valves for ushing tanks controlled by a ball-float or other suitable means.

One object of my invention 1s to reduce the velocity of the water before leaving the su 1 ipe to overcome so far -as possible thspdyisgreeable hissing sound caused by water under pressure w en dlscharged into the flushing tank'. r- 0 With the foregoing and other objects. 1n view which will a pear as the description proceeds the invent1on further resldes 1n the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention hereln dlsclosed without departing from thespirit of the same.

In the drawings accompanying-this spec1- iication:

Figure 1 is a side elevation of the device with the ball-float and supporting rod `broken away.

Figure 2 is a vertical cross-sectional view of the device showing arts in elevation.

Figure 3 is a vertica cross-sectional view of a modification of the device with parts in elevation.

Figure 4' is a horizontal cross-sectional view taken on or about line 4 4 of Figure 2.

Figure 5 -is a horizontal cross-sectional view taken on or about line 5-5 of Fi re 3.

Referring now to the letters of re erence placed upon the drawings:

A, denotes the bottom of a flushing tank of usual construction provided with an opening to receive a water supply pipe B havin a flange B', overlapping a washer B2 ad]acent the inner wall of the tank. C, is a washer fitted to the pipe B on the underside of the tank and D is a nut screwed u on the pipe to secure the latter to the wal of the tank. E, denotes a nipple screwed into the Ipipe B, upon which is screwed a re1a tive y long stand-pipe F having a spiral flange F integral with its outer wall.

A valve casin H is secured to the up r end of the stan -pipe F and a hollow valle seat member G is confined within the casing. A spider G secured to the casing H supports the valve seat member in alignment with the stand-pi with whichit communicateS, uthe spi er G having a central screw-threaded a rture g and other o enings g between t e central aperture an the casi wall. The valve seat member G is exteriorly screw-threaded intermediate its ends for working fit in the screw threaded aperture g of the spider. The casin H is contracte at its upper end and a p unger H is slidably mounted in this contracted upper end of the casing and is provided at its lower end with a valve .disk h .carried thereon by a collar h screwed onto the lower end of the plunger. The collar h projects from the lower endof the plunger to ernbrace the upper end of the valve seat member and to position said disk h on the upper ind of the valve seat member, as shown in hush pipe I depends from the casing H and closely encircles the perimeter of the flange F forming with the latter a spiral passage to secure the noiseless delivery of water into the tank. J, is a yoke journaled upon trunnions h2 extending laterally from the valve casing, and sleeved upon lugs H, integral with the closure plug. J is an adjustlng screw extending through the wall of the yoke and adapted to bear upon the casing to limit the travel of the closure plug in an opening direction. Jz is a rod screwed into the end of the yoke upon the end of which is mounted the usual ball-float (not shown) controlling the operation of the valve. l-I3 is a ackmg ring carried by the closure plug H to prevent the esca e of water at the upper end of the plug. II-l denotes an openin into the valve casin from which leads t e usual rell pipe H In the modification shown in Figure 3 the hush pipe is fitted to a stand-pipe F provided with lon 'tudinally disposed outer ribs F" having staggered connecting passa es F between the ribs to cause the water de ivered through the ball-cock to pass back and forth throughout the length of the hush pipe that it may spend its velocity before leaving the pipe.

xoo

Having indicated Y the several parts by reference letters the construction and operation of the device will be readily understood:

Upon the water being discharged from the flush tank in the usual manner the balloat (not shown) controlling the operation of the closureV plug H will be depressed thereby raising the closure .plug and thus admitting water through the ball-cock which upon leaving the valve body is forced to take the splral passage provided in the hush pipe thereby checking its velocity before entering 'the tank thus eliminating the disagreeable lhissing noise common to many Hush tank installations.

In the modification shown in Figure 3 the. water instead of taking a spiral course around the stand-pipe is caused to follow a passage up and down the pipe whereby its force is spent before leaving the stand-pipe.

It will be noted that in the present construct-ion that a hush pipe of relatively high altitude' is provided having a long spiral or other devious passage thereby securingthe gradual expenditure of the velocit-y of-the water before it passes into the ushing .tank thus insuring a practically noiseless delivery of water into the latter.

Having thus described my invention what I claim is:

1. In a supply means for flushing tanks, a coupling adapted to extend through the bottom of the tank and be rigidly secured thereto, a stand-pipe connected to and rising from the coupling, a hush-pipe opening at its lower end into the tank and sleeved upon the stand pipe, the latter having means for cooperation with the hush-pipe to provide a relatively long channel between said pipes through which the water passes prior to its discharge into the tank, a valve casing secured to the upper end of the hush-pipe, a

spider secured to the interior of the casingy intermediate the ends of the latter and insage of water from the stand pipe into the hush-pipe and thence to the flushing tank, and a ioat lever connected to the plunger.

2'. In a supply means for flushing tanks, a stand 4pipe adapted to be operatively connected to the tank, a hush-pipe opening at its lower end into the tank and sleeved upon the stand pipe, means between the standpipe and hush-pipe to provide a relatively long channel between said pipes through which the water passes prior to its discharge into the tank, a valve casing secured to the upper end of the hush-pipe, a spider in the casing having a screw-threaded aperture, a hollow valve seat member disposed in vertical alignment with the stand-pipe and provided intermediate its ends with a screwthreaded portion having working it in the screw-threaded aperture of the spider, and a float controlled plunger mounted lin the casing in alignment with the valve seat member and slidable toward and away from cooperative relation with the outer end of the valve seat member to govern the passage,

of water from the stand-pipe into the hushpipe and thence to the flushing tank.

In testimony whereof, I sign .this specification in the presence of two witnesses.

WILLIAM SHERWOOD.
